    ◆Innovative Sealing Design
    Upgraded from traditional grooved rubber strips, the valve body now uses elastic rubber encapsulation instead of groove-mounted seals. This eliminates the difficulty of replacing worn-out seals by integrating the seal into the valve body structure.
    ◆Field-Replaceable Sealing System
    When seals wear out, on-site replacement is possible with tool-free installation/dismantling design. Easy maintenance minimizes production downtime and ensures quick turnaround.
    ◆Bi-Directional Double-Layer Sealing

    Upgraded from single-direction seals to dual bi-directional double-layer sealing strips, enabling:
    —Full pressure resistance in both flow directions
    —Zero leakage in reverse flow conditions
    —30% higher sealing durability than traditional single-seal designs

    ◆Compact Design & Stable Operation Across Pressures
    Small installation space, low working pressure, high pressure ram no vibration, no noise.
    ◆Straight-Through Channel with Minimal Flow Resistance
